Gravity PDF fills a need in the Gravity Forms ecosystem when simple screen or email responses no longer suffice. This a great free base plugin and you only need to spend money if and when you need to customize further.

Also the support is top-notch and Jake frequently participates in the support process to keep an eye on issues. The overall customer experience is very, very good. Review collected by and hosted on G2.com.

The hardest thing about Gravity PDF is the customization route. While you can pay them to do all of the work for you, our team likes to be more hands-on but FPDF is not the world's easiest library.

This is in no way the product's fault, just a comment that you will need to be a pretty decent programmer if you want to write your own customizations into existence. Review collected by and hosted on G2.com.
